That makes sense. The guy I bought it from told me that one of the people who came and looked at the truck told him that they thought it was a long bed that had been cut down.
The truck actually doesn't look too bad the way it is, but it's not what I want. I'm shooting for the "resto-rod" look that appears mostly stock on the outside but with updated drivetrain and interior.
Oh well, I guess I need to start looking for the whole bed.
